LEG REST.

Application filed October 17, 1921 Serial no. 508,195.

surgical appliances and it has for one of its objects to provide a device that can readily be carried from place to place as required.

A further object is to provide a device that is particularly designed for supporting a foot or limb of a patient while being treated or the surgical bandages are being applied or removed.

A further object is to provide a device that can be readily adjusted in order to make the patient as comfortable as possible.

A further object is to provide a combined cabinet and surgical appliance for the purpose of having a convenient receptacle for storing the necessary implements and medicincs andthe usual materials that are neces sary for such work.

A further object is to provide means whereby the appliance can be readily folded into av compact or small compass.

A further object is to provide a suitable basin or receptacle for receiving or catching any liquids or pieces of bandages that may occur during the use of the appliance.

Referring to the drawingsin detail:

1, 2, and 3 designate the frame which supports the appliance'and is preferably formed on angle iron. The legs 1 which are provided with a pad or cushion at their lower ends to prevent the appliance from slipping as indicated at 4, while the legs 2 are provided with rollers 5 whereby when the appliance is to be moved it is only necessary to elevate one end and roll it along the floor. 6 designates a basin or receptacle which is supported by means of the flange 7 engaging the upper ends 8 of the legs as shown in Fig. 2. Slidably mounted in the frame is the drawer 9 which is supported on the. cross bars 10. This drawer is for receiving any of the usual materials which a surgeon uses in dressing wounds or any other of the necessary surgical implements. 11 designates sockets'mounted on the sides of the legs of the fra me work for receiving the brackets 12 i which supports a swinging shelf. These brackets permit the user to place thereon the implements or other articles whichare being used.

Referring now more in detail to the stirrup construction which supports the limb or foot of the patient, 13 and 14 designate sockets that are attached to the opposite ends of the frameworkand in these sockets are located the slidable rods 15 and 16. 17 are thumb nuts for holding the rods 15 and 16 in different positions of adjustment. The rod 15 is further provided with a bolt 18 and a thumb nut 19. Slidably supported on the rod 15, is the upwardly extended curved arm 20 having aslot 21 which slot receives the bolt 18 and therefore permits this arm to I be raised or lowered and adjusted or held in any suitable position or height. Attached to the arm 20 is a rod 21 by means of a pin 22. This rod is rectangular in cross section, as shown in Fig, 5. 23 designates a second arm at the opposite end of the appliance which is pivotally connected to the rod 16 at 24. The pivot 24 therefore permits the arm 20 and rod 21 to be raised or lower since it would swing about this point as a center. Secured to the upper end of the arm 23 is a tubular member into which the rod 21 telescopes. 26 and 27 designate as a whole the two stirrups which support the limb of the patient. These stirrups are formed of four arms 28, 29, 30 and 31. The arms 28 and 29 are spaced from the arms 30 and 31 along the rods 21 and25. The lower ends are formed with enlargements and disk shaped plates 32. 28 and 31 are plates to prevent the outward movement of the arms of the stirrups. Une of these is formed with projections 33 which engages correspondingly shaped recesses 34 in the oppositely located plate. 35 designates a fixed flange on the tubular member 25 and against which the arm 31 bears. For the purpose of forcing the arms 28 and 29 outward and the arms 30 and 31 against the flange or stop 35 a coiled expansion spring 36 is located be-- tween these pairs of arms as shown in Fig. 3 whereby the two pairs of arms are frictionally held indiflerent positions of adjustment but at the same time permits them to be swung either into an open or closed position as indicated in Figs. 2 and 5 by reason of the ribs 33 engaging therecess 34. Engaging the upper ends of the two pairs of arms and connecting the same are the swinging bars 37. These bars are for the purpose of receiving the loops in the fabric or band 38. They are made to swing as shown in 1 Fig. 3 whereby the fabric may be put on or taken 0E as desired and a.so to permit the arms to be folded in opposite directions indicated by the arrows 39 in Figs. 2 and 5. The two pairs of arms which constitute the stirrups may be folded as a whole into the dotted lineposition indicated in Fig.1. Thestirrup 26 may be slid or moved along the rod 21 to accommodate the patient which isbeing treated as indicated by the arrows 40. The stirrup 27 is constructed in the same manner. as that already described in connection with stirrup folded into the dotted line position indicated at 41. It is of course obvious thatthe stirrup 27 may be located at different longitudinal positions along the tubular member 25 but is preferably shown and used in the position indicated against the upwardly extened bar 23. A coiled expansion spring 42 is used for thesame purpose as the spring 36. For the purpose of protecting the springs 36 and 42 a tube 43 is used. This tube also serves as a spacer or limit device for the two pairs of arms which constitute the stirrup. The center part of the tubular member 25 indicated at 25 serves as the hand e by means of which the appliance may be carried by the user when desired from place to place.

It is to be understood that the applicant 26 and may be does not limit his appliance to any particular size of parts or material as it may be made portable or otherwise.

It is also to be understood that the stirrup members 38 are so constructed that they may be readily changed for sanitary purposes or reasons as for example by forming loops at their ends. to slip over the rods 37.

Referring to Fig. 6 44 and 45 indicate tubular rods for receiving and retaining the stirrup fabrics or bands 46; The rod 44 is provided with a slot 44. In the slot 44' is placed one end of the. fabric and the hemmed end 46 prevents the fabric from pulLing through. 47 designates a, swinging device which is pivotedto the arm 31 at 47 and is provided with a cross bar 47 formed with teeth 47 which engage the fabric for clamping the free end whereby the length between the rods 44 and 45 may be adjusted to the comfort of the wearer. When weight is applied to the center portion of the fabric 46 the teeth 47 of the bar 47 will pinch the fabric between it and the tube 45. To release and adjust, it is only necessary to pull downward on the free end 46 In Fig. 7 the rod 45 may be mounted for rotation in bearings 48 for winding the free end of the fabric 46 thereon. It is held in different positions by means of the pin 49 which passes through the openings 50 and 51 in the bearing 48 and the end portion 49. By means of the construction shown in Figs. 6 and 7 the comfort of the user may be accomplished.

What I claim is:
